Iyo RF coaxial switch chishandiso chinoshandiswa muRF uye microwave masisitimu ekutaurirana kumisikidza kana kushandura kubatanidza pakati peakasiyana coaxial tambo nzira. Inobvumira kusarudzwa kweiyo chaiyo yekupinza kana nzira yekubuda kubva kune dzakawanda sarudzo, zvichienderana neinoda gadziriro.
Zvinotevera maitiro:
1. Kukurumidza kushandura: RF coaxial switching inogona kukurumidza kushandura pakati peakasiyana RF masaini nzira, uye nguva yekuchinja kazhinji iri pamillisecond level.
2. Kurasika kwekuisa pasi: Chimiro chekushandura chakabatana, nekurasikirwa kwechiratidzo chepasi, chinogona kuve nechokwadi chekufambisa kwehutano hwechiratidzo.
3. Kuzviparadzanisa kwepamusoro: Shanduko ine yakakwirira yekuzviparadzanisa, iyo inogona kunyatso kuderedza kupindirana pakati pezviratidzo.
4. Kuvimbika kukuru: Iyo RF coaxial switch inotora zvinhu zvemhando yepamusoro uye yakakwirira-chaiyo yekugadzira tekinoroji, ine kuvimbika kwakanyanya uye kugadzikana.
Qualwaves Inc. zvinhuRF coaxial inochinja nekushanda frequency renji yeDC ~ 110GHz uye hupenyu hunosvika mamirioni maviri kutenderera.
Ichi chinyorwa chinosuma 2.92mm coaxial switches yeDC ~ 40GHz uye SP7T~SP8T.
